Strip applying device

摘要

A device including means for removing a protective liner from elastic reflex-light reflective strip material, means for applying a length of the strip material to a tire casing, and means for separating the applied length from a supply length of the strip material. The means for removing the liner includes means in driving engagement with the liner, the speed of which can be varied via rotation of a helical strip to match the rate of strip application. Rotation of the helical strip is caused by movement along the strip of a carriage on which the liner is separated from the strip, which movement of the carriage is caused by the accumulation or decrease in the amount of liner between the carriage and liner drive means when the ratio of liner movement to strip movement increases or decreases. The means for separating the applied length of strip material includes means for perforating the strip material at a location related to the leading end of the applied length, and means activated after the strip material is applied at the perforation for clamping the strip material in the device and pulling the supply length of strip material away from the applied length so that they separate at the perforation.
